Dear Robie, actually, it is quite easy to reproduce during an update from saucy to trusty and i suspect that this bug will even strike when you do a clean trusty install.
Nevertheless, i reproduced this issue with a fresh saucy install: 1. install saucy using http://at.mirror.archive.ubuntu.com/ubuntu/dists/saucy/main/installer-amd64/current/images/netboot/mini.iso 2. install openssh-server and samba-server during installation (via tasksel?) 3. reboot and verify samba status: # root@ubuntu:~# smbstatus Samba version 3.6.18 PID Username Group Machine ------------------------------------------------------------------- Service pid machine Connected at ------------------------------------------------------- No locked files 4. add a user and view list the available shares # root@ubuntu:~# smbpasswd -a ubuntu New SMB password: Retype new SMB password: # root@ubuntu:~# smbclient -L \\localhost -U ubuntu Enter ubuntu's password: Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.6.18] Sharename Type Comment --------- ---- ------- IPC$ IPC IPC Service (ubuntu server (Samba, Ubuntu)) print$ Disk Printer Drivers Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.6.18] Server Comment --------- ------- UBUNTU ubuntu server (Samba, Ubuntu) Workgroup Master --------- ------- WORKGROUP UBUNTU 5. do-release-upgrade -d (remove obsolete packages; reboot) 6. verify samba access (FAILS!) --ubuntu@192.168.122.233's password: Welcome to Ubuntu Trusty Tahr (development branch) (GNU/Linux 3.13.0-18-generic x86_64) * Documentation: https://help.ubuntu.com/ System information as of Sat Mar 22 08:50:31 CET 2014 Last login: Sat Mar 22 08:41:59 2014 from rbi ubuntu@ubuntu:~$ smbstatus Samba version 4.1.3-Ubuntu PID Username Group Machine ------------------------------------------------------------------- Failed to initialize session_global: NT_STATUS_ACCESS_DENIED Service pid machine Connected at ------------------------------------------------------- Failed to initialize session_global: NT_STATUS_ACCESS_DENIED Failed to traverse sessions: NT_STATUS_ACCESS_DENIED No locked files ubuntu@ubuntu:~$ smbclient -L \\localhost -U ubuntu Enter ubuntu's password: Domain=[WORKGROUP] OS=[Unix] Server=[Samba 4.1.3-Ubuntu] tree connect failed: NT_STATUS_ACCESS_DENIED Please let me know in case you require this system as a KVM/QEMU disk image.
